Abstract

A support for the armature being tested, permits the latter to be rotated, about its horizontal shaft axis, by a separate electric motor drive. Whilst in this supported state, a contact block is introduced into the vicinity of the commutator such that five spring loaded rods or feelers (16,11,12,12,14) make good electrical contact with five consecutive bars (6,1,2,3,4) of the exemplified six-bar commutator, connecting to a winding composed of coils (RB1,RB2-RB6). The contact between bar and winding, the resistance of which is to be evaluated, is indicated as (RS1,RS2-RS6). A generator (20) applies a voltage (V1) between contacts (11 and 12) and a second generator (21) with voltage regulator (22) applies a voltage (V2) also between the contacts (12 and 13).
